TL;DR: the patch LGTM (but I agree with Sergey regarding the whitespace in statement). At the same time I see a small rationale for such complex logic, considering the upcoming LuaJIT build system refactoring and the fact your solution doesn't work in the most general case (but nobody asked for it). As we discussed before we have three possible cases of configuration: 1. do not intersect with ("true" OOS build) 2. is (in source build) 3. is a subdirectory within ("quasi" OOS build) The first case is very simple: you need only run luacheck within , since all paths in .luacheckrc are considered relative to the current working directory. This issue is solved via WORKING_DIRECTORY property and you even resolve all symlinks for . The second case is a bit tricky: there might be autogenerated Lua chunks (e.g. jit/vmdef.lua). These files are not considered as Lua sources per se, so there is no need to check these files with luacheck. Then simply exclude the whole recursively and the issue is completely gone. Unfortunately, it's not. The third case is the most complex one, though it doesn't look so. In case of in source build, those autogenerated Lua chunks are build within and there is no other way than explicitly exclude those files from the list to be checked with luacheck. We don't face this case, since everything within third_party/luajit/ is excluded from check. I even haven't faced this in LuaJIT submodule, since src/ directory is excluded from the check, so src/jit/vmdef.lua is not checked. Hence if there would be an autogenerated Lua chunk violating .luacheckrc rules in scope of Tarantool src/ directory, you had to explicitly suppress it to make luacheck happy. I hope my arguments are clear enough. Let's return to LuaJIT build system enhancements. If out of source build is used now, LuaJIT submodule is fully copied to the , so all Lua sources are moved in Tarantool source tree. Hence they are checked with luacheck and there are many warnings produced. In scope of #4862 I reimplemented LuaJIT source tree manipulations, so all LuaJIT sources are left within third_party/luajit despite to the chosen build type. As a result, there is a single Lua file violating luacheck warnings: jit/vmdef.lua that is generated within Tarantool source tree (in "quasi" out of source build case). It looks to be much easier to explicitly exclude this single file via --exclude-files option and leave the comment with the rationale, since you complex solution doesn't work in a general case. Anyway, this is not a major point against applying your changes, but rather common sense. Everything except the point above is OK, so if you are sure with your solution feel free to proceed with the patch.
